I'll be putting roof bars on my car in the near future, and heard that due to the design they can wear away at the paint if carrying heavy loads/left on for a long time. I was wondering if I could buy small sheets of that anti-stone chip stuff people have on leading edges of bonnets etc to cut up and use as I need?

Thanks, James.
